MICHAEL E, GEBEL, or AMOUR, LSOUTH DAKOTA ELECTRIC SOLDERING ARBON.

i Application nled Harsh 30, 1928. Serial No 266,011.

My present invention has reference to an electric soldering iron 'inwhich a stick of carbon is employed as the soldering point,

. the numer and in which the carbon is heated by a source of electricitobtained from a batte in which t e return wire to the attery 1s clampedupon the article being soldered, and my rimary object is the provisionof an artlcle or this purpose that shall be' of a simple construction,may be safely and conveniently used, and wherein the soldering pointsmay be arranged at varying points with respect to the handle and stem ofthe improvement so that solder may be ap lied to the parts of articlesthat are inaccessi le to the ordinary solderin iron.

A. girther object is the provision of a novel clutch for clampin one ofthe conductors in a position to pro er y contact with the solderingpoint toget er with a novel chuck for securing the point on theimprovement.

Other important objects will resent themselves as the nature is betterun erstood, reference bein had to the accompanying drawin which orm partof this application.--

y El the drawings;

Figure 1 is a' substantially central longitudinal sectional view throughtheimprovement.

Figure 2 is a side elevation illustratin the manner in which 'theimprovement is Fi re 3 is a. detail view showing a curved chucEl c rangea carbon point atan angle with respect to the longitudinal plane of theiron.

Figure 4 is a similar view illustrating a further modification. v

Figure 5 is a sectional view approximately on the line 5-5 of Fi re 1.

, Referrin now to e drawings in detail, 1 designates the handle of theim rovement. The handle is of some suitablg insulating material, woodfor instance. The`handle has its ends reinforced by metal ferrules 2which are flanged to contact with both the body and ends of the'saidhandle.

` Let in one end ofthe handle there is a. sleeve but has its outermember 3. The sleeve is interiorly threaded ortion enlarged to provide aocket 4 for a c osely woundwire ard 5.

ere is screwed through the threa ed portion of the sleeve 3 and receivedin the pocket 4 a metal tube 6. The guard 5 is screwed yon theprojecting end of this tube and on the outer end of said tube there isscrewed the hollow stem 7 of the improvement. The stem and also- .bonpoint 16.

screwed on the stem of the iron to :irv is held on the tube by a locknut`8'which is screwed on the said stem and disposed opposite thek endof the tube.

The outer end of the stemis both interior] and exteriorly threaded, theexterior threadis merging into an-'enlarged or shoulderl portion 9. l

APassing through the guard 5 and tube 6 there is an encased conductor 10and fixed to this conductor and extending through the hollow stem 7there is a metal rod 11 which is preferably of copper. y The rod 11 isexn.

tended into the threaded end of the stem 7, and there is screwed in thesaid threaded end a plug 12. v The plug has a central bore therethroughand from its outer end 13 the said plug is slitted longitudinally atright angles.

The plug isthus in the nature of aclutch Vmember. The plu Ais slightlyta ered as is the inner threade portion of tie-stem 7.

The plug is of metal and, therefore, a c011- i ductor of' electricity.lThe Screwed home effectively clutches the rod 11.

Screwed upon the exterior portion of the outer end of the stem 7 thereis a chuck sleeve 14 vand this sleeve is desi ned to have receivedtherein and to frictions ly enga e` therewith the inner and reducedconical en 15 of a car- The encased conductor 10 has on its outer endaspring clip or clam -17. The second encased conductor is indicated bythe numeral 18 and has both of its ends provided with spring clips 19and 20, respectively, which are similar to the spring clip 17. A portionof the conductor 18 has its casing wound with or otherwise secured to apart of the conductor 10. The clips 17 and` 19 are designed to beclamped upon the poles of a battery 21 and the clip 20 is designed to besoldered. As soon as the carbon is brought a ainst the article 22 thecircuit will be comp eted and the carbon point'l will be heated plugwhen -clamped on the edge of an article 22 tobe v `mit of the solderingoperation. In Figure 3 A curved but has extended therefrom a tubularportion 26 in which the reduced end of the carbon point 27 is received.u

The simplicity of my improvement, the construction thereof and theadvantages will, it is thought, be understood and ap reciated by thoseskilled in the art when the ore-going description has been carefullyread in connection with the accompanying drawing, but

obviously I do not Wish to be restricted to the recise details as hereinset forth and, thereore, hold myself entitled to make such changestherefrom as fairly fall within the scope of what I claim.

Having described the invention, I claim: 1. A carbon point electricsoldering iron,

including an insulator handle having a tube tor having a spring clamp onthe outer end thereof and a second conductor having spring clips on bothof its ends.

2. A carbon point electric solderingr iron including an insulator handlehaving a tube extending longitudinally therethrough, a sleeve in one endof the handle screwed on the tube, a flexible guard received in thesleeve and screwed on the said end of the tube, a hollow metal stemscrewed on the second end of the tube, a lock nut screwed on the stemfor sustaining the vsame on the tube, a conductor received'through theguard and tube, a metal rod fixed on one end of the conductor andreceived in the stem, a metal splitY clutch member screwed in the end ofthe sleeve Iand clamping the rod, a chuck sleeve screwed on the stem,and designed to receive therein one end of a carbon point which contactswith the clutch, said conductor having a spring clam on the outer end,thereof and a second con uctor having spring clips on both of its ends.

In testimony whereof I aix my signature.
